Abstract

A reflectarray reflects an incident wave in a desired direction. The reflectarray includes a substrate including a surface which is perpendicular to a predetermined axis; and at least first and second element groups, wherein the first and second element groups are disposed on the substrate, and include elements that reflect a radio wave. The first element group and the second element group reflect the radio wave with corresponding reflection phases which are different from each other. The radio wave enters while forming an angle other than 0 degrees with respect to the predetermined axis. The elements included in the first element group reflect the radio wave with a first reflection phase, and the elements included in the second element group reflect the radio wave with a second reflection phase, wherein the second reflection phase is different from the first reflection phase.
